It's been a while since I posted here. I purchased the Cyba quad tips and CF diffuser and installed them more than a year ago. I couldn't be happier with the looks.

During the install the shop seemed to have a hard time cutting and welding the new tips without cutting off the exhaust valve that comes stock behind the tip on the driver's side so we cut it off. I liked the sound (a little louder, more gurgling, a little droning) but after all these months I would like to quiet it down back to stock levels.

Initially I thought the sound was louder because of the increased tip size cross area but after reading some threads I realize it is most likely the missing exhaust flap valve. The problem is the valve is gone (trashed it at the shop back then) and even if I was able to get it back I'm not sure it would fit.

So... does anyone here have the Cyba quads installed and was able to keep the stock exhaust valve? Is it possible to get the valve portion anywhere to try to weld it back on? Anyone here care to sell it?

Thanks!

Im glad you posted this, im looking at the same exact setup, but would prefer to keep the exhaust valve there if possible, looks like Im going to have to plan on dual exit instead of quad.

bump.

would love to know as well.

[lxlarry]

bump i'm wondering the same question

The shop I installed my tips at kept the valve. They had to cut some of the piping of the cyba tips though so they wouldn't stick out so much to compensate.

Anyone else wanting to resolve this?

Is there anyway to get an exhaust bypass valve? I don't have the stock one that was removed anymore...

Do you want one? I have one for sale PM me

I kept mine intact. Cyba Quads

Finally I was able to fix my droning! I got a bypass valve, basically had to talk a seller on ebay on cutting the exhaust tip and selling and shipping only this part:




I then went to the muffler shop and they were able to cut off the tip, remove some tubing and accommodate the bypass valve. The change in sound is subtle but it doesn't drone anymore on the highway and it isn't so loud. Very happy with the mod! Or "unmod" I guess .

I wonder if the valve would cut down the drone on a car with no muffler

good thread I'm in the process of ordering some quad tip's. Ill make sure I keep the valve or it's a no go.
